2) Search for the next section and make sure the following has been specified as to the default keystore:

#
# Default keystore type.
#
keystore.type=Windows-MY

The above sections show the correctly modified content within the java.security file to enable the support for IBM CAC and thus Smart Card Log-in ability within the Rational Team Concert Eclipse client

NOTE: If you are using IBM Rational Team Concert Eclipse client version 4.0.3, use keystore.type=JKS

For more information on why using JKS key store refer to defect Defect 268980

"Regarding SHA-224 support, SHA-224 offers less security than SHA-256 but takes the same amount of resources. Also SHA-224 is not generally used by protocols and applications. The NSA's Suite B standards also do not include it. We have no plans to add it on future versions of our CSPs."

So to fix this problem, update the java.security file to disable SHA224withRSA.

Verify that the Microsoft Visual C++ 2010 Redistributables are installed.

In Microsoft Windows Control Panel -> Add or Remove Programs search for the installation

NOTE: 32bit Operating Systems will only require the 32bit version of the redistributable. 64bit Operating Systems will require both the 32bit and 64bit versions of the redistributable. See the following links to the redistributables:

WARNING: If you fail to verify that the Microsoft Visual C++ 2010 Redistributables are installed, the RTC Eclipse Client will immediately exit without any error message or core, even when sending the debug output to a log or java console. This is a sign that the redistributables are missing, and you should immediately check to see that they are installed. As noted above, if this is a 64bit Operating System, you will need BOTH the 32bit and 64bit redistributables

Verify the IBM JRE version bundled within the RTC Eclipse Client:

In Rational Team Concert Eclipse client Help -> About Rational Team Concert -> Installation Details

As seen above, the JVM vendor is IBM, the major version is 1.6 and the service release is SR13 FP1: Therefore, the above SDK will support IBM CAC. If the Service Release is below 1.6 SR12, then you will require an upgrade to the SDK bundled with the IBM Rational Team Concert Eclipse client. You can download it from Jazz.net
